Before shipment, TAI calibrates the analyzer for your application when
feasible. Calibration data is listed in the Appendix. Prior to calibration, TAI
checks the electronics of the analyzer and makes all of the necessary internal
printed circuit board adjustments. Calibration is performed to determine the
proper zero and span settings, and also to verify that the analyzer response is
linear.
After calibration, TAI makes a lengthy stability check to insure that the
analyzer performs within all specifications. We advise that you recalibrate
your equipment as part of start-up for the following reasons:
1. During shipment, it is possible that components have been jarred
out of position or damaged.
2. Your process may be of a proprietary nature. Beyond checking
electrical stability, TAI is unable to make a meaningful calibra-
tion of the system, requiring these adjustments to be made by
you.
3. In other cases precise calibration can only be made with the
analyzer connected to your process stream.
In any case, it is important that you calibrate the analyzer when it is
first installed. Zero checks should be made routinely once or twice a week
and span calibration should be performed weekly, at first, and monthly
after reproducibility is assured.
